The very first level in the game. It consists of a very basic layout, with hieroglyphs of the Item Shopkeeper on the walls that teach Wario his basic moves. Simple enemies like Marumen and Spear-Masks appear in this level. In the Normal and Hard game modes, the switch is right at the end of the level (thus making it far more easier to reach the vortex in time). However, in S-Hard mode, the Switch is found near the beginning.

The boss of the Entry Passage is Spoiled Rotten, a youthful eggplant-like creature. Two Eggplant Warriors appear as bodyguards at the beggining of the fight, which behave exactly like Totsumen and can be defeated the same way. Spoiled Rotten is initially defenseless, but after being rammed rammed a few times, it will throw a tantrum and turn savage, bearing teeth that harm Wario on contact. Only ram attacks from behind will work from then on. Defeating Spoiled Rotten will grant access to the four main Passages.
